To all 'whom it may concern: i

Be it known that I, 'CHARLE'S A. CAMP BELL, a citizen of the United States, residing in Philadelphia, Pennsylvania, have in: v

Vented certain Improvemnts in Horseshoes, of which the following is a specific&- tion. V y

My invention relates tohorseshoes of the all metal type, and the object of my invention isto provide e horseshoeof this character with e lower or wearing 'acewhch willdecrease the tendency of the Shoe to slip or slide upon paved road surfaces, and will furnish the shoe with an improved I have found that if' a shoe be provided, at the toe and heel portions, with suitable poekets or pocket-forming depending portions, Snow or dirt will pack therein when theshoe is in use, and

that seid packed Snow or dirt will provide rough gripping sui-faces, and take the 'place of ordinary calks. Pockets for this purpose may be formed in different ways, but 'as the result of a long series of experiments, I have devised the Construction hereinafter described, and find it peculiarly well suited to most normal conditions.

A further object of myinvention is to provide a Shoe of thischaracter, having the improved grit retaini'ng pockets, that may he readily bent, cold or hot, for the purpose of fitting it to wide or narrow hoofs, without distortlon and without closng the nail holes initiaily formed therein. i

These and other features of my invention are more fully described hereina'ter, reference being had to the secompanying drawings, in which: V

Figure 1, is a plan View of the lower or hearing face of one 'orm of horseshoe embodyng my invention; Fg; 2, is'e sectional,

view on the line 2-2, Fig. 1; Fig. 3, is 'a sectionalview on the line 3-3, Fig. i; i, is a sectional View on the line r-et, F l; Fig. 5, is a sectional View 011 the line -5, Fig. 1; Fig. 6, is a View similar to Fg. l, illustrating a slightiy modified Construction within the scope of my invention, and Fig. 7, is a view similar to Figsrl and 6, illustrating' another arrangement within the scope of my nventon.

My improved shoes are provided with means at the toe portions 'and att'he heels that willserve as retainin -poekets in whch snow or dirt will pack w en the shoe is in use; suh packing of Snow or dirt serving to prov de a rough grppng surface( n .the *form of horseshoe shown in Fig. l, an isloated poeket 1 is provided at the toe 'of the shoe. This pocket is fformed by transverse depending; wlls 2, 9?, at the forward outer portion of 'the same and at the nner portion themel: respe'c'iveiy; such walls ooforming to 'the ourvature ofthe forward or toe portio ofthe Shoe' and .ham ing their outer surface SIi htly heveled or converging'inwardly so that the extreme width of the `pasket fol-med by hese Welle longitudinally of the Shoe at 'their hearing surfce is less then the toe portion of the Shoe with which they are integraly con-` nected. These transverse depending wals 2 2 are joined by end walls suhstentielly Parallel with the longitudinal azis of the shoeyend the outer surface-of said endfimlls may the heveled to. the same degree es the transversewalls. "The inner surfaces of the several walls forzhng this toe poeket are also slighty bevel ed; such beveling adding to the effective use of the structure, by ing the wlls a comparatively sharp contact-ing surface for engagement with the ground and being also. desirahle in manufecture `ofthe Shoe ;since the .letter is a drop forging. u

The quarters or loranches l of the ehoe exted i'earwardly in the usual curved liges to conform with the hoot' of a horse, and are suhstmtially the same `width through 'out and of the same thickness; such guar- 'cers -terminating in rounded heels The quarters are punched as indicated at 6 for the reception of nails for 'securing the Shoe to the hoof in the usual manner; but the usual'creasing or fullering is omitted.

In the form of Shoe illustrated in Fig. 6, A ,one of theside walls forniing the toe Pocket and parlleling the longitudnal aXis of the Shoe; that indicated at 3 for instance, isthickened outwardly as clearly indioated at 7 in the drawings, for the purpose of providing additional weight; such thiekened, portion when the Shoe is appled to the hoof lying 011 the outside or to the right of shoes -for the right feet, and to the outside or left of shoes for the left feet, and is designed to cles that are strained when the shoe is only worn on one side. In addition, it adds extra wearing material to the side walls of the toe poeket without, however, affectng the value and utility of such toe pocket.

At the termination of the quarters I provide snow and dirt retaining means as shown in Figs. 1, 2,` 3, et seg., and these may be in the form of dependingproyections or calks 8 set diagonally with respect to the longitudinal aXis of the shoe to avoid catching in the joints of paving, or as shown in Fig. 7 ,thesede'pending retaining means may be in the form of pockets 9; continuous depending wallsfbeing carred by the Shoe adjacent the heels to form the same.

Inthe form of Shoe shown in Fig. 1, I provide'sets of three depending pro ections or calks 8 adjacent theend of each quarter or branch, and these calks are Setinward from the extreme end of the heel'so as to bring the support of the hoof afio rded thereby forward of 'the 'heel and avod pressure on the point of the latter. These calks or projections depend from `the under surface of the Shoe to the same depth as the walls of the 'toezpocketso that the hearing surfaces of the sameare in the same plane as the bearing surfaces of the `walls at the toe of the shoe forming such toe pocket. calks have beveled walls as indicatedgand they are' narrower at their bearing surface 'than at the point of junctionwiththe quarters or branches of the shoe, as clearly indicated in the drawings. In the form of horseshoe shownin Fg 6,

the outer portiono-f the shoe; that is to say, the right hand branch orquarter of a right shoe and the left hand branch or quarter of a left Shoe, is provided with three depending pro-jections or calks of the 'same character as illustrated in' Fi'gs. 1, 2, et seg., while the opposite side of the shoe is only provided with two calks, which may be slightly thinner. The additional` calkon the outer branch or quarter of the shoe adds Weight on one side ofthe Shoe in' connect tion .With the increased weight of the thick 'ened wall 3 of the toe pocket, and the omisson ,of a calk on the opposite branch or quarter of the shoe lightens the opposite side of the Shoe so that horses tending to wear their shoes unevenly have this defeet corrected` by the' employment of a shoe :of this character.- u

In' the structure shown 'in- Fig. 7, the heel iportio ns of the shoe are provided with pockets of a character' substantially` like 'that shown at the toe portion' of the Shoe;

such' heel pockets being made: up of depending walls B which followthe curvature of the'branch'or quarter at the 'heel "portion 'ofthe .shoeand are joined bydiag -oinaiy positi oned walls 8 -`which`lie substan- Such depending projections or tially in the same position .asthe outside or terminal calks of the sets shown in' Fg. 1."

In addition, inthestructure shown in Fig. Y 7, I mayprovide the toe portion with a, plurality of longitudinal depending walls 3 intermediate the end walls 3 whereby a pluraltyof .pockets `1 are formed ,at such point.` All of these pockets will have 'bvi eled walls as described, facilitating the withdrawal of the -dies'in manufacture. p y i An important featureflof 'mymventon lies nin thefactthat a shoe made in aci- 5 cordance 'Wlth my nvention and having the i depending pocketed portions in the same planeat toe and hee1s,:prov1d1ng'an even the course of i bearing surface, has unobstructed branches v or quarters intermediate these pocketed por-` tions, which branches or quarters are of-the same -thickness and of substantially the same width.

and receivesand retainssnow 'er dirt, which packs firmly therein and- 'ormstheabearing surface for the 'tOeportio-n of the Shoe, and. the transverse walls 3 prevent the paoked material from washingzthrough or away, from the pocket in wet weather.

may more readily retain the packed snow or dirt.

The 'Shoe can be made 'by -drop-forgingg and itlwill be noted" that the branohes" `or q uarte`rs-of 'the shoe are free from projeetons, and, consequentlyzthere is nothing ,to

interfere with the bending or shaping: of the Shoe by the -blacksmith" in: fittng 'the same to the horse, either hot 'or cold.

As' this application possesses matter in; common'wth an application` fi led by'- "me February 4,- 1914," Serial No. 816588, it is not to be treated as a continuation of said prior application as far as the commonsubjectmatter is concerned.

No claim is made herein to the structure .shown in Fig. 6, the same forming the subject of an application for patent filed by me April 20, 1915, Serial No. 22,698. r

I claim:

l. As a new article of manufacture, a horseshoe of substantially uniform thickness throughout its entire eXtent having separate heel extensions, with a pluralty of walls depending from the lower surface of said shoe at the central portion of the toe thereof to form an isolated pocket for the reception of snow, dirt, etc., to provide a bearing or wear surface; certain of said walls following the inner and outer contour of the shoe, the quarters of said shoe being substantially unobstructed r'earwardly from said toe pocket, and projections depending from said quarters forward of the points of the heels, said projections having hearing' or ground contacting portionsin the same plane a's the depending walls of the toe pocket and providing additional means for the reception of Snow, dirt, etc., to form hearing or wear surfaces.

2.
